That the FLYi A319 right seat went was bid very senior shouldn't be a surprise to anyone. The usual way pilots advance to an A319 or 737 is to leave (generally as a captain) from a regional airline (often flying CRJs) and becoming an FO of an A319 or 737 (at 1st year rates) at another airline.
So the same thing is happening at ACA except the pilots don't have to leave the regional to access the A319.
